To all whom it may conccrle: dislodgmcnt of the pin P is prevented by Beit known that I, HENRY DEITZ, acitizen projection A and slot P, asdescribed. of the United States, residing at Chicago, In coupling, theend B of the knuckle B 55 county of Cook, State of Illinois, haveinrotates against the lower end of the pin P 5 vented a new and usefulImprovement in Carand swings it backward, thereby permitting Couplers,of which the following is a specithe knuckle to revolve in place,whereupon fication. the pin P drops back to its normal vertical Myinvention relates to that class of coupposition between the end B" ofthe knuckle 6o lers generally known as the Master Carand the wall A ofthe casting A, the pin re- Builders standard of verticalhook coupvolvingon the point A of the casting A as a lers; and the objects of myinvention are to center, as shown in Fig. 2, the lip P engagproduce acoupler composed of a minimum ing said projection A The location of thisnumber of parts, that are strong, durable, center is such that thecenter of gravity of and easily manufactured, and yet having the the pinat all times is such as to cause the I 5 merits that will beparticularly described pin to fall in the desired vertical position.

Fig. 2 is a vertical longitudinal in atriangular opening P which opening P sectional view on line 2 2 ofFig. 1. Figs. 3 (see Figs. 7 and 8) is located at one side of and 4: areviews similar to Fig. 2, showing the pin, producing, as it were, a sidedraft in the locking-pin in a different position.

Fig. 6 is a sectional plan view on est position. The pin isaided in being lifted line 6 6 of Fig. 3. Fig. 7 is a front vertical inthis inclined position bymeans of the lower sectional view on line 7 7of Fig. 1. Fig. 8 end of the slot P being beveled out, as is So is afront vertical view of the locking-pin. shown in Fig. 7, whereby whencoming in 0 In the drawings, A designates the main contact with theprojection A the lower end body casting of the coupler, and B the of thepin is forced outward, causing it to pass knuckle-piece. These twocastings are made over the end B of the knuckle, and upon the in theordinary method to conform to the release of the tension of the chainupon the Master Car-Builders lines,but being provided pin P it fallsdownward and rests upon the 3 5 with a locking device, as I will nowdescribe. end of the knuckle, as is shown in Fig. 3.

thereby clearing projection A from the slot In the event that theknuckle should be P, whereupon on the further lifting of the locked homeat the time when a coupling is pin P from the coupler projection Apasses desired to be made a device is provided 011 10c downward througha recess P of the pin P, the bottom of casting A to enable the brake- 50as shown by Fig. 4, and thus the pin P is man to throw open the knuckleready for permitted to be withdrawn from the casting coupling withoutplacing his hands in a po A 5 but in the use of the coupler accidentalsition likely to'be injured by the accidental keepers Hof the casting A,connected by pin H engaging a slot in a lever 11, pivoted at H to thebottom of casting A and provided with a projection H, which extendsupward through a slot in the casting A and engages the back of theknuckle, whereby by pulling on the handle H the projection H is thrownagainst the knuckle and forces it outward, the pin P having previouslybeen lifted. A projection A on the interior of the casting A, Fig. 2,serves as a stop for the pin P in swingin g backward.

On the end B of the knuckle B there is a projection B which engages aprojection A in the casting A, Fig. 1, when the knuckle is locked home,which engagement of said projections prevents the removal of the knucklein the event of the pivot-pin 13" being removed accidentally when thecars are coupled together, the peculiar position of the locking-pin Pholding the projections B and A together even in the absence of the pinB, which may at some time prevent accident to the train.

Vhat I claim is 1. The combination with a draw-head and a knucklepivoted thereto to swing horizontally in a recess in the same, of alocking-pin arranged to be lifted vertically above the knuckle and alsopivotally supported in front of its own line of gravity to be swungtemporarily rearward, in a vertical plane, by the knuckle passing tocoupled position, and means whereby such lifting automatically swingsthe lower end of the pin from said plane, to rest upon a suitablesupport adapted to prevent its descent.

2. The combination with a recessed drawhead and a knuckle pivotedthereto to swing in the recess, of a locking-pin having in front of itsline of gravity a pivotal support allowing the pin to be swung rearwardby the knuckle and also to be lifted above the plane of the latter, aprojection extending from the draw-head into the plane or path of thepin, said pin being provided with a channel, to receive the projection,adapted to allow both swinging and raising of the pin While limiting thelatter movement.

3. In a coupler of the class described, the combination with a draw-headand a knuckle pivoted therein upon a vertical axis, of a lockin g-pinpivotally supported upon a horizontal axis, located above the path ofthe knuckle, and swinging rearward in a plane intersecting said path,and means whereby lifting said pin throws its lower end laterally out ofsaid plane and over the knuckle when the latter is in coupled position,substantially as and for the purpose set forth.

4. In a coupler of the character described the combination of alocking-pin, of means for raising said pin vertically in unlocking, ofmeans for inclining the said pin when raised in a manner that it mayengage the end of the knuckle as shown, with projections on the end ofsaid pin and knuckle for insuring the holding of the pin upward by theknuckle.

5. The combination with the recessed and slotted draw-head, of theknuckle pivoted to swing in the recess, the centrally-pivoted leverhaving upon one arm a projection extending through the slot in thedraw-head to force the swinging of the knuckle, and having its other armslotted, and the bar mounted to slide transversely upon the draw-headand provided with a projection engaging in the slot in the lever toactuate the latter.

In witness whereof I have hereunto subscribed my name, on this 29th dayof October, 1895, in the presence of two subscribing witnesses.

HENRY DEITZ.
